Stella 3.2 - 模擬器

http://stella.sourceforge.net/

Atari 2600 emulator for Windows has been updated. Changes:
- NOTE: because of the many event-related changes in this release, all event
mapping should be reset to defaults after starting Stella for the first time.
As well, because of other internal changes, older save-state files are no
longer valid.
- Many improvements to joystick handling code, particularly for analog axes.
Navigating the UI should be much smoother now, and remapping events to analog
axes should be less 'twitchy'.
- Added ability to assign and remap 'combo' events in emulation mode. Combo
events are basically a sequence of normal events (up to 8) that are generated
from a single event (ie, one button on a joystick could generate up to 8
events). Updated Input Settings UI to access and modify these events.
- Default mappings are now available in UI and emulation mode for the first
'hat' detected on a joystick/gamepad. Related to this, a hat now works
exactly like an axis in UI mode (holding down a direction continues that
direction until the hat is released/centered).
- Several major improvements to the debugger:
-- the disassembler can now process multiple entry points, and caches entry
points as they're encountered (ie, the disassembly isn't 'reset' each time a
bank change occurs or you exit and re-enter the debugger);
-- preliminary support for disassembling from zero-page RAM;
-- re-added ability to change banks with the 'bank' debugger prompt command
and within the ROM disassembly UI;
-- user labels in disassembly are now supported again;
-- 'runto' command is now case-insensitive, and shows a progressbar while
searching through the disassembly;
-- the debugger window can be resized between ROM loads (previously, the app
had to be restarted);
-- fixed bug in Distella disassembler output, where it sometimes generated
addresses above $FFFF;
-- a vertical line separates the disassembly from the raw bytes.
- Fixed behaviour of SWCHB and SWBCNT; pins set to output now remember the
values previously written. Some ROMs use this functionality for extra
storage. Special thanks to Omegamatrix of AtariAge for advice and test ROMs
in this area.
- Fixed bug when reading from illegal TIA addresses; a Space Invaders hack
was showing pink enemies instead of white ones. Again, special thanks to to
Omegamatrix of AtariAge for advice and test ROMs in this area.
- Fixed bug in handling INPT4/INPT5 latches from VBLANK; a least one ROM was
working in Stella when it didn't on real hardware.
- Added 'ramrandom' commandline argument, which is used to randomize all RAM
in the system; otherwise, the RAM is zeroed.
- Added 'finishing touches' to some of the UI descriptions, giving a better
explanation of the functions. Related to this, certain options now show a
message box explaining the option in further detail (particularly the ROM
Audit mode). As well, when starting Stella for the first time, a prompt
appears to select a ROM directory.
- Fixed bugs in the ROM launcher when viewing certain PNG images not created
by Stella. Related to this, the official PNG library is now included in the
Stella codebase (version 1.4.3). Also added composite snapshots for those
ROMs which consist of several games. Thanks go to Buzbard of AtariAge for
these images.
- Added several fixes for crashes on 'small' systems (those systems where the
maximum resolution is less than 640x480).
- Tweaked bankswitch autodetection for 0840, DPC+, E7 and UA schemes.
- Improved F8 bankswitch autodetection for Yars Revenge in 8in1 ROM.
- Updated DPC+ bankswitch scheme to latest specifications.
- Snapshots taken in continuous snapshot mode are now timestamped, so older
files are never overwritten.
- Fixed a TIA segfault that could occur with certain ROMs.
- The 'center' application window functionality can now be changed without
having to restart the application. Related to this, mouse positioning bugs
when using the Linux version in OpenGL mode with SDL 1.2.14 have been fixed.
- Reworked the manual, dividing it into 'Getting Started' and 'Advanced
Configuration' sections. It still contains the same info as before, but
hopefully in a better organized way.
- Updated Help dialog; it was showing incorrect info for some OSX shortcuts.
- Updated OSX build script to not crash when a previous build is detected,
and to properly handle filenames with spaces.
- Updated included ZLib to latest release version (1.2.5).
